AGL Loy Yang

LY Main_banner 


Each year, AGL Loy Yang produces approximately 15 TWh of electricity, enough to power over 2 million Australian homes. It is an integral part of Australia's national electricity market. 

AGL Loy Yang supplies approximately 30% of Victoria’s power requirements. 

Acquired in June 2012, AGL Loy Yang comprises the 2,210 megawatt Loy Yang A power station and adjacent Loy Yang coal mine. AGL Loy Yang uses brown coal, supplied exclusively by the adjacent open cut mine, as the fuel source to generate electricity. The mine has an annual output of approximately 30 million tonnes of coal.

The power station and mine operate 24 hours a day, seven days a week.

Notice: Hyland Highway to be closed to allow relocation of travelling stacker

AGL Loy Yang wishes to advise the community that the Hyland Highway between Traralgon Creek Road and Flynn’s Creek Road will be closed to public traffic from 6pm Friday night 17th March until 6am Monday morning 20th March to allow relocation of a travelling stacker.

We recommend that motorists travelling to and from Gormandale during this time follow the detours on the Princes Highway and Flynn’s Creek Road.

We thank you for your patience in allowing us to carry out this important work which will involve the travel of a 2,100 tonne, 10 storey high piece of machinery, known as TS4, from Loy Yang’s external overburden site to the base of AGL’s mine.

Logistics and more information

The 19 kilometre journey will take nearly four weeks with the stacker moving eight metres a minute. It will begin its journey on 13 March and is expected to finish in mid-April. To ensure a safe journey, a significant amount of work has already taken place.

The trip has involved five years of extensive planning and consultation with representatives from AGL Loy Yang and a number of local contractors and external stakeholders including VicRoads, Emergency Management Victoria and Basslink. We have developed a rigorous engineering and safety management plan.

The TS4 stacker will relocate to the base of the mine to move excess materials like clay and soil known as overburden, back into areas of the mine where coal is no longer extracted.

This will assist with natural stabilisation of the mined area, reduce noise and dust from the overburden site, reduce fire risk at the base of the mine and assist with progressive rehabilitation.

A path has been cleared, power lines will be dropped and the highway will be covered with disused conveyor rubber belts to protect it. Despite its 2,100 tonnes, TS4’s footprint (weight per square metre) is less than that of a typical 4-wheel drive due to its width and weight distribution. 

As part of AGL Loy Yang’s long-term mine plan its travelling stackers, known as TS4 and TS5, will both be relocated to the base of the mine.

Development and maintenance

The power station includes four 500+ megawatt turbo generators which were brought into service between 1984 and 1988. Until the year 2000 Loy Yang had a base generating nameplate capacity of 2000MW. Upgrades through major maintenance programs and plant enhancements have taken generation capability to over 2200 megawatts.

A seven year, $60 million ICMS conversion project completed in October 2014, converted all AGL Loy Yang operating units from an ageing analogue system to a state of the art digital control system. The project has been vital to ensuring energy security and reliability of supply to Victoria.
